----------------------------------
Could you gave me the ticket and let me try, please?
> Allow comments in CSV format without having to ignore parse errors
> ------------------------------------------------------------------
>
> Key: FLINK-21583
> URL: https://issues.apache.org/jira/browse/FLINK-21583
> Project: Flink
> Issue Type: Improvement
> Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile), Table
> SQL / Ecosystem
> Affects Versions: 1.12.1
> Reporter: Nico Kruber
> Priority: Not a Priority
> Labels: auto-deprioritized-major, auto-deprioritized-minor
>
> Currently, when you pass {{'csv.allow-comments' = 'true'}} to a table
> definition, you also have to set {{'csv.ignore-parse-errors' = 'true'}} to
> actually skip the commented-out line (and the docs mention this prominently
> as well). This, however, may mask actual parsing errors that you want to be
> notified of.
> I would like to propose that {{allow-comments}} actually also skips the
> commented-out lines automatically because these shouldn't be used anyway.
